Company Overview

About ProbablyMonsters

ProbablyMonsters is an independent video game holding company founded in 2016 by Harold Ryan — former president and CEO of Bungie (creator of Halo and Destiny) — and headquartered in Kirkland, Washington. The company's model is to provide capital, infrastructure, technology, and operational support to enable independent game development studios to build AAA-quality games while maintaining stable, sustainable working environments. ProbablyMonsters acts as a parent company to multiple game studios, each of which develops its own original IP.

Business Model & Competitive Advantage

ProbablyMonsters has raised $200 million in total funding to support its studio portfolio. Its first developed title, Flintlock: The Siege of Dawn — an action RPG developed by its Insurgent Games studio — launched on Xbox Game Pass and other platforms in July 2024. This launch validated ProbablyMonsters' model of incubating a new studio from scratch to commercial game release. The company's second studio, Cauldron Studios, is developing a first-person shooter game that is currently in development. A third studio is also in early-stage development.

Competitive Landscape 2025–2026

ProbablyMonsters' approach addresses a persistent challenge in the game industry: AAA game development requires hundreds of millions of dollars and hundreds of employees over multi-year cycles, a process that often leads to crunch culture, studio instability, and creative burnout. By providing studios with long-term capital and shared services — including technology, HR, legal, and recruiting — ProbablyMonsters aims to enable game teams to focus on creative development without the existential financial pressure that typically drives unsustainable practices at independent studios.
